have suitable curb ramps at each end or where there are level differences more than 19 mm (3/4 inch).

Public pedestrian routes are designed for universal access and are free of obstacles. Sidewalks should be firm and levelled paving with joints no greater than 6 mm (1/4 inch) wide and 13 mm (1/2 inch) tall.

Winter weather

Snow and ice accumulation and drifting snow are major problems for persons using mobility aids or persons with physical limitations. Accessible entrances use radiant heating to automatically clear ice and snow, where timely maintenance and snow clearing may be a problem.

Snow should be removed to expose edges of the sidewalk at the curb to avoid mobility aids catching the edge and rolling.
